Winterizing a pressure washer

I believe most recommend that you pour an antifreeze solution into the pump when storing such units. Supposedly it not only prevents damage due to freezing, but stops corrosion. At least that is what my unit recommends.

I wouldnt use normal green antifreeze, they make one that is pink (and in a clear bottle) and used in rv's etc. My manual stated something different about the two in the pink stuff was the way to go. I will look to see what the differences were.

You should run out the gas or use Sta-bil.

You must winterize the pump. Purchase RV antifreeze or Windshield antifreeze solvent. Rig a funnel to the water input of the washer. With ignition off slowly crank the engine/pump until you see the antifreeze come out of the outlet. You are done.

Blue water works fine also. That's what we use since we use the pressure washer daily all winter. Just pump bluewater through it, and good to go. It's the cheapest solution.

we use stabil in the gas, take the pressure line off and blow the water out of it. pour anti freeze into the pump and spin it over till it comes out the other side. ..... or you could just run it with antifreeze till it comes out the pressure hose.i would also look at the oil in the pump to be sure its not milky with water.change if necc. lucas

Whatever you do, do not use ethylene glycol as the antifreeze. (green)

Why not? Do tell.

Ethylene glycol is corrosive and can damage the pump. RV antifreeze is not corrosive and additionally lubricates the pump.

That is bullshit. What do you think is in your car?!?! We've treated the pressure washer where I work on occasion (when the people doing didn't know any cheaper) with automotive antifreeze. It can't hurt it.

Rust, and plenty of it in the cooling passages. (ethylene glycol)

Tell that to pump manufacturers.
